Or Freeze Welsh Expansion plug – Engine core plugs A core plug is a thin piece of metal either in a cup or dish shape which is used to block off a hole or some form of opening on an engine block or cylinder head that was made in the manufacturing process.
Here at Engine Core Plugs All core plugs are manufactured slightly oversize by 0.25mm – 0.40mm (0.010” -0.015”) which is the interference fit required to seal them snug in whatever opening they are being installed.
